[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, the novel floating nut deburring mechanism includes a worktable 1. A pressing cylinder 2 is installed at the top of the worktable 1. The piston rod of the pressing cylinder 2 extends through to the bottom of the upper top plate of the worktable 1. A pressing mechanism extending to the top of the upper top plate of the worktable 1 is installed at the bottom of the piston rod of the pressing cylinder 2. A column 17 is fixedly installed at the top of the lower bottom plate of the worktable 1. A fixing plate 18 is fixedly installed at the top of the column 17. Feeding mechanisms are fixedly installed on both sides of the top of the fixing plate 18. A grinding mechanism is connected to the output end of the feeding mechanism. A rotating mechanism extending through to the top of the fixing plate 18 is fixedly installed at the bottom of the fixing plate 18.

[0018] In this embodiment: First, the product: nut 9 is placed on the top of the output end of the rotating mechanism. Then, the clamping mechanism is started to clamp the nut 9. After being clamped, the rotating mechanism is started, and the rotating mechanism drives the nut 9 to rotate. Then, the feeding mechanism is started, and the feeding mechanism drives the grinding mechanism to move towards the nut 9. After the high-speed rotating grinding mechanism comes into contact with the nut 9, the grinding mechanism removes the burrs on the nut 9.

[0019] Please refer to this carefully. Figure 1 and Figure 3The pressing mechanism includes a movable plate 10 fixedly connected to the bottom end of the piston rod of the pressing cylinder 2. Two sets of sliding rods 11 are slidably connected inside the movable plate 10. A connecting plate 12 is slidably connected to the outer wall of each set of sliding rods 11. A compensation spring 14 is abutted between the top of the connecting plate 12 and the bottom end of the movable plate 10. The compensation spring 14 is sleeved on the outer periphery of the sliding rod 11. Guide shafts 3 are fixedly connected to both sides of the top of the movable plate 10, extending through to the top plate of the worktable 1. The guide shafts 3 are slidably connected to the top plate of the worktable 1. A rotating pressure block 13 is rotatably connected inside the connecting plate 12 through a bearing. The rotating pressure block 13 is aligned with the rotating shaft 5 in the vertical direction.

[0020] In this embodiment: after the nut 9 is placed, the pressing cylinder 2 is activated, and the pressing cylinder 2 pushes the moving plate 10 to move downward. At this time, the moving plate 10 drives the guide shaft 3 to move downward, and at the same time, the moving plate 10 drives the connecting plate 12 to move downward until the rotating pressure block 13 is in close contact with the top of the nut 9.

[0021] To avoid a hard collision, after the rotating pressure block 13 contacts the top of the nut 9, the continuously operating downward pressure cylinder 2 drives the moving plate 10 to continue moving downward. At this time, the moving plate 10 and the first sliding rod 11 slide relative to each other, and the first compensation spring 14 is compressed.

[0022] Please refer to this carefully. Figure 1 and Figure 3 The feeding mechanism includes slide rails 20 fixedly installed on both sides of the top of the fixed plate 18. A slide rod 21 is slidably connected to the inner wall of the slide rail 20. The slide rod 21 is integrally formed with a slider slidably connected to the slide rail inside the slide rail 20. Screws are rotatably installed at both ends of the inner wall of the slide rail 21. The screws are threadedly connected to the slider. A passive pulley is installed at one end of the screw. The passive pulley is connected to the driving pulley through a transmission belt. The driving pulley, the passive pulley and the transmission belt are located in the inner cavity of the transmission box 6. A forward and reverse motor 19 coaxially connected to the driving pulley is installed on the outer wall of the transmission box 6.

[0023] In this embodiment: the forward and reverse motor 19 is started, and the forward and reverse motor 19 drives the active pulley on its output end to rotate. The active pulley drives the passive pulley to rotate through the transmission belt. The rotating passive pulley drives the screw connected to it to rotate. When the screw rotates, it drives the slider to move axially along the slide rail 20. The moving slider drives the grinding mechanism to move towards the nut 9 through the slide rod 21.

[0024] Please refer to this carefully. Figure 1 and Figure 2The rotating mechanism includes a rotary motor 4 installed at the bottom of the fixed plate 18. The output end of the rotary motor 4 is coaxially connected to a rotating shaft 5 via a coupling. The rotating shaft 5 extends through the top of the fixed plate 18 and is rotatably connected to the fixed plate 18 via a bearing. A nut 9 is fitted onto the top outer wall of the rotating shaft 5.

[0025] In this embodiment: after the nut 9 is tightened, the rotary motor 4 is started, and the rotary motor 4 drives the rotary shaft 5 to rotate through the coupling. The rotating rotary shaft 5 can drive the tightened nut 9 to rotate.

[0026] Please refer to this carefully. Figure 1 and Figure 2 The grinding mechanism includes a second sliding rod 15 slidably mounted on one end of the sliding rod 21. A mounting base is fixedly mounted on the outer wall of the second sliding rod 15. A second compensating spring 16 abuts between the mounting base and the sliding rod 21. The second compensating spring 16 is sleeved on the outer periphery of the second sliding rod 15. A file 7 is mounted on the upper outer side of the mounting base, and a lathe tool 8 is mounted on the lower outer side of the mounting base.

[0027] In this embodiment: during the axial movement of the slide rod 21, the slide rod 21 drives the mounting base connected to it to move synchronously, and the mounting base drives the file 7 and the cutting tool 8 to move synchronously. When the file 7 and the cutting tool 8 come into contact with the nut 9, the parting line on the nut 9 can be polished.

[0028] The second sliding rod 15 and the second compensating spring 16 are designed to prevent hard collisions caused by excessive movement of the feeding mechanism, thereby avoiding the occurrence of defective products due to this situation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
